Filed: 1995-05-09
Abstract: PURPOSE: To provide an optical amplifier capable of more faithfully amplifying a signal beam compared with a usual example and inducing excitation light from a high output excitation light source to a core of a smaller size. CONSTITUTION: An optical isolator 11 transmits the signal beam in one direction, and outputs it to a second optical fiber cable 102 through a first optical fiber cable 101, and on the other hand, the excitation light generated by the excitation light source 16 is transmitted to be outputted through a third fiber cable 24 having tapered core and cladding converting from a larger pore size to a smaller pore size connected to the excitation light source 16. A multiplexer 15 reflects the incident excitation light, and excites the signal beam by making it incident on the second optical fiber cable 102, and passes through the signal beam amplified by inductive emission in the second optical fiber cable 102 by excitation. The optical isolator 12 transmits and outputs the signal beam outputted from the multiplexer 15 in one direction.

Title: Schmitt trigger circuit
Inventor: TANAKA NORISHIGE
IPC: H03K3/353
Filed: 1986-05-15
Abstract: PURPOSE:To obtain a Schmitt trigger circuit with less number of components by using a signal at an output terminal of the 2nd inverting circuit so as to apply conductive control to the 1st transistor (TR) thereby retarding the level change of the signal at the output terminal of the 1st inverting circuit. CONSTITUTION:When a potential of an input signal VIN is lowered and reaches a circuit threshold voltage VthC of a CMOS inverter 13, a P-channel MOS TR 11 starts conducting. A VOUT signal of an output node 18 of a CMOS inverter 17 is still at a high level and a TR 20 is conductive. Thus, the charging of an output node 14 of the TR 11 is disturbed by a path comprising TRs 19, 20 in addition to an N-channel MOSTR 12, and the time when a signal at the output node 14 of the inverter 13 reaches the circuit threshold voltage VthC of the inverter 17 is retarded. Then the substantial threshold voltage when the output VOUT signal is inverted to a low level is brought into a voltage lower than the circuit threshold voltage VthC of the CMOS inverter and a prescribed hysteresis characteristic is obtained. Further, the titled circuit consists of six MOS TRs in total.

Filed: 1980-08-15
Abstract: PURPOSE: To make it easy to fix the blade on and off the disc rotor by setting a slit to be extended to the axial direction to a piece for fixing a dovetail of the blade or for positioning of the blade.  
     CONSTITUTION: A slit 10 is set to be extended to the axial direction on a dovetail shaped piece 9 and a taper screw 12 is spirally joined with the screw hole 11. After fixing a position of the axial direction by inserting the piece 9 in the rotor's groove, the taper screw 12 is screwed into. The piece 9 is elastically transformed by the slit 10 to tighten the taper screw 12 and to be fixed through an increase in the surface pressure. Thus, adjustment of the blade position is easily allowed to be made to lead to a simple fixing of the blade on and off the disc rotor. Further, reliance of the fixed blade may be increased because of a large contact area between the disc rotor and the blade's dovetail part.
